Panasonic's Nano Surface Coating technology is adopted to minimize the reflection at entire visual light range (380nm-780nm) by applying the extra-low refractive index coating with nano-sized structure on the surface of the lens. It results in the super clear image with dramatic reduction of ghost and flare.

** The time for focusing on the subject is measured with the DMC-GF3 to move the lens position to ""2m"" from ""infinity"" position at wide-end. Panasonic measurement method. ****/

*** Measured with DMC-GF3. The time required to start exposure after the shutter button is fully pressed after the lens position is moved from “infinity” to “2m” at wide-end. ****/

H-PS45175E, What Digital Camera, Recommended, September 2012"Probably the cleverest parts of this lens are tucked away inside, leaving only a modest but very competent face visible to the world"
